Aged images and the like are displayed on the display units 414, 514, and 614.

  The maintenance plan table creation unit 102e creates a maintenance plan table that indicates when the life years have elapsed since the start of operation for each BIM part (each part) as the maintenance work timing (replacement timing).

  Based on the maintenance plan table and the maintenance route information, the maintenance route determination unit 102f performs maintenance work for each part to be worked on a predetermined maintenance work day in the maintenance plan table in an available time zone of the area where the part is located. The maintenance route is determined as in The maintenance route information includes an available room time zone that is input for each area in the building.

May be. For example, the maintenance route may be determined so that the movement distance of the worker is the shortest within a range that satisfies the conditions of the room availability time zone of each area. Further, even if the moving distance is not the shortest, the maintenance route may be determined so as to avoid the congestion time zone of each area.

  The maintenance cost table creation unit 102g creates a maintenance cost table indicating the maintenance cost corresponding to the maintenance plan table using the maintenance plan table and the cost information in the parts information. At that time, the cost information acquired by the code analysis unit 102h may be used.

  The code analysis unit 102h uses a one-dimensional code (for example, a barcode) or a two-dimensional code (for example, a QR (Quick Response) code (registered trademark)) attached to the part itself or a storage container corresponding to the part. By analyzing a code read by a dedicated reader (not shown), it is possible to obtain part identification information, standard life years, and cost information. Similarly, the code analysis units 402h, 502h, and 602h in the terminal devices 400, 500, and 600 are also based on, for example, a one-dimensional code or a two-dimensional code attached to a part itself or a storage container corresponding to the part. By analyzing the code read by a dedicated reader, it is possible to obtain part identification information, standard life years, and cost information.

  For example, in the shared server device 100, based on the BIM parts and the standard life years, if a maintenance plan table that indicates when the standard life years have passed since the start of operation for each BIM part is created as a maintenance work timing, It is possible to reduce the labor for making a maintenance plan in consideration of the life span of building parts.

  However, if the standard lifespan of a part is used as it is, the part replacement timing (maintenance work timing) is determined and the part replacement is performed, a malfunction due to a part failure that cannot be assumed with the standard lifespan can occur. . For example, when the elevator is an elevator, if the elevator is used frequently, the life of the part may be shorter than the standard life year, and the use of the part (BIM part) in the car due to the failure of the part (BIM part) A person may be trapped.

  In addition, if the standard service life of a part is used as it is, the part replacement timing (maintenance work timing) is determined and the part replacement is performed, and if the part has a longer service life than the standard service life, Useable parts will be discarded. That is, since the running cost of the parts is unnecessarily increased, there is room for improvement in terms of effective use of the parts (BIM parts).

  Therefore, in the present embodiment, in the BIM system 1, the level of use frequency of the BIM parts is calculated, the actual life years are predicted based on the BIM parts, the standard life years, and the use frequency levels, and the predicted lifespan is calculated. By determining the replacement timing of the BIM parts based on the number of years and creating a maintenance plan table, the maintenance plan can be made more efficient while improving the accuracy of the maintenance plan.

  Specifically, in the shared server device 100, the storage unit 106 further includes a calculation formula file 106d, monitoring data 106e, group management measurement data 106f, periodic inspection data 106g, usage frequency level management information 106h, and object information database 106i. It is remembered.

  The calculation formula file 106d stores calculation formulas used when executing simulations related to elevators. For example, calculation formulas necessary for calculation of movement of human objects (traffic simulation) and calculation of traffic volume of elevators (traffic simulation). The calculation formula necessary for is stored. The calculation formula file 106d stores calculation formulas necessary for calculation of the degree of deterioration of parts (deterioration degree simulation) based on periodic inspection data (for example, an image of the surface state of the parts) for each part of the elevator. In addition, the calculation formula file 106d may store various threshold values, parameters, sample data, and the like necessary for each calculation.

  The monitoring data 106e is data received by the communication control interface unit 104 from the terminal device 600 on the security company side via the network 300 and stored in the storage unit 106, for example. The monitoring data 106e includes an operation history of the elevator monitored using the remote monitoring system. When the elevator is an elevator, the monitoring data 106e may include a history of the time at which the elevator car is assigned as a car that responds to a hall call and / or car call, and the time at which it arrives at a predetermined floor. When the elevator is an escalator, the monitoring data 106e may include a history of the time when the escalator starts operating and the time when the escalator stops operating.

  For example, when the elevator is an elevator, the group management measurement data 106f includes information on the operation time of the elevator obtained when group management control of a plurality of elevators is performed in the shared server device 100. For example, the group management measurement data 106f can include the operating time of each elevator. For example, in group management control, when the control unit 102 receives a landing call from a landing button via a predetermined communication line, the control unit 102 registers the landing call and sends a car call from the button in the passenger car via the predetermined communication line. Upon receipt, the car call will be registered. The control unit 102 assigns one of a plurality of elevator cars as a car responding to the hall call and / or car call, and causes the car to land on a predetermined floor. The control unit 102 can calculate the time from the timing at which the hall call or the car call is assigned to the car to the timing at which the car is landed and opened, as the operating time. The management measurement data 106f can be added and updated.

  The periodic inspection data 106g is data received by the communication control interface unit 104 via the network 300 from the terminal device 400 on the owner side or the terminal device 500 on the equipment supplier side and stored in the storage unit 106, for example. The periodic inspection data 106g is data relating to the periodic inspection of the elevator parts performed by the person in charge on the owner side or the equipment supplier side, and may include information on the usage state of the parts. The periodic inspection data 106g can include, for example, a component characteristic (electrical resistance or the like) indicating the usage state (degradation state) of the component, and includes an image of the surface state of the component indicating the usage state (degradation state) of the component. And can include an internal state image (ultrasonic image, X-ray image, etc.) of the component indicating the usage state (degraded state) of the component.

  The object information database 106i stores object information related to a human object or the like that can move within the BIM model of a building. For example, object information related to a human object is information that defines a three-dimensional model imitating a human that can move according to a predetermined condition. The object information related to the human object includes, for example, movement conditions including at least a starting point and a destination for each human object, in addition to shape data for constructing a three-dimensional model imitating a human. The object information related to the human object is referred to, for example, when the movement of the human object on the flow line is simulated by the processing of the control unit 102. The object information may be read from an external storage device (not shown), may be input via the input unit 118, or may be acquired via the network 300. It may be.

  The control unit 102 further includes a simulation unit 102i, a calculation unit 102j, and a prediction unit 102k as functional configurations. Each functional configuration in the control unit 102 may be realized by hardware (as a circuit disposed in the control unit 102) or by software (executed in the control unit 102 by executing a program on a memory). It may be realized as a functional module), or a part of it may be realized by hardware and the remaining part may be realized by software.

  The simulation unit 102i can perform various simulations.

  For example, the simulation unit 102i acquires the building-specific information 106a1 included in the BIM model database 106a from the storage unit 106, and acquires the information on the human object included in the object information database 106i from the storage unit 106. The simulation unit 102i acquires from the storage unit 106 a calculation formula necessary for calculating the movement of the human object included in the calculation formula file 106d. The simulation unit 102i performs a traffic simulation using a calculation formula based on the building-specific information 106a1 and the human object information, and simulates the movement of the human object. The simulation unit 102i can generate the flow line information 106a2 according to the simulation result, and can store the flow line information 106a2 in the BIM model database 106a. The flow line information 106a2 is information related to the trajectory of the movement of the human object in the virtual three-dimensional space (building model), for example, information related to the flow line of the user of the elevator.

  For example, the simulation unit 102i acquires the building-specific information 106a1 and the flow line information 106a2 included in the BIM model database 106a from the storage unit 106. The simulation unit 102i acquires from the storage unit 106 a calculation formula that is included in the calculation formula file 106d and that is necessary for calculating the traffic volume of the elevator. The simulation unit 102i performs traffic simulation by a calculation formula based on the building specific information 106a1 and the flow line information 106a2, and simulates the traffic volume of the elevator. The traffic volume of the elevator may include the number of operations of the elevator per predetermined time unit. The simulation unit 102i generates information on the traffic volume of the elevator according to the simulation result and supplies it to the calculation unit 102j.

  For example, the simulation unit 102 i acquires from the storage unit 106 the aged deterioration image included in the component aged deterioration image storage unit 106 c. The simulation unit 102i obtains, from the storage unit 106, a calculation formula necessary for the deterioration degree simulation included in the calculation formula file 106d. The simulation unit 102 i acquires the periodic inspection data 106 g from the storage unit 106. The periodic inspection data 106g includes information on the usage state of the BIM parts (parts) obtained by the periodic inspection of the BIM parts (parts). The simulation unit 102i performs a deterioration degree simulation by a calculation formula based on the periodic inspection data 106g, and simulates the deterioration degree of the BIM parts (components). For example, when the aged deterioration image is an image of the surface state of a part in a deteriorated state and the periodic inspection data 106g is an image of the surface state of the current part, the simulation unit 102i displays the aged deterioration image and the current part image. And the degree of deterioration of the BIM part (part) according to the degree of approximation. Can be requested. Alternatively, the aging degradation image is an image of the internal state (ultrasonic image, X-ray image, etc.) of the component in the deteriorated state, and the periodic inspection data 106g is an image of the internal state of the current component (ultrasonic image, X-ray image). The simulation unit 102i obtains a difference image between the aging degradation image and the current component image, calculates the total level of each pixel, etc. The degree of deterioration of the BIM parts can be determined according to the degree of approximation. The simulation unit 102i generates information on the degree of deterioration of the BIM parts (parts) according to the simulation result and supplies the information to the calculation unit 102j.

  The calculation unit 102j can calculate the use frequency level of the BIM parts by various processes. The calculation unit 102j determines the usage frequency level of the BIM parts in response to the standard life years input for the BIM parts being received from the terminal devices 400, 500, and 600 via the network 300 by the communication control interface 104. Can be calculated.

For example, the calculation unit 102j acquires the traffic volume of the elevator from the simulation unit 102i. The calculation unit 102j calculates the usage frequency level of the BIM parts based on the traffic volume of the elevator. When the traffic volume of the elevator includes the number of operations of the elevator in every predetermined time unit, the calculation unit 102j sums up the number of operations of the elevator in every predetermined time unit from the previous part replacement to the present, and replaces the previous part replacement. The cumulative number of operations of the elevator after that can be calculated. For example, when the cumulative number of operations of the elevator after the previous part replacement is M, the elapsed time after the previous part replacement is Δt, and the standard number of operations per unit time is N, the calculation unit 102j The use frequency F of the BIM parts can be calculated by the following formula 1.
F = M / (N × Δt) Equation 1

For example, the calculation unit 102j obtains information about the operating time of the elevator included in the group management measurement data 106f from the storage unit 106. The calculation unit 102j calculates the usage frequency level of the BIM parts based on the operating time of the elevator. For example, if the cumulative operating time of the elevator after the previous part replacement is ΔT, the elapsed time after the previous part replacement is Δt, and the standard operating rate per unit time is R, the calculation unit 102j is: The use frequency F of the BIM parts can be calculated by the following formula 2.
F = ΔT / (Δt × R) Equation 2

For example, the calculation unit 102j acquires information on the degree of deterioration of BIM parts (components) from the simulation unit 102i. The calculation unit 102j calculates the use frequency level of the BIM parts based on the degree of deterioration of the BIM parts (parts). For example, when the degree of deterioration of a part and the cumulative number of operations of the elevator since the previous part replacement are approximately linearly proportional, the degree of deterioration of the BIM parts (parts) is D and conversion from the degree of deterioration to the cumulative number of operations Assuming that the coefficient is K, the elapsed time since the previous part replacement is Δt, and the standard number of operations per unit time is N, the calculation unit 102j calculates the BIM parts usage frequency F by the following formula 3. it can.
F = (D × K) / (N × Δt) Equation 3

  The calculation unit 102j can assign any of the five steps as a level according to the calculated use frequency F. For example, when α is an arbitrary positive number smaller than 1, if 1−α <F <1 + α, the usage frequency F is at a standard level, and the calculation unit 102j sets level 3 to the BIM part. Can be assigned. If 1−β <F ≦ 1−α (β is an arbitrary positive number larger than α and less than 1), the usage frequency F is at a level slightly lower than the standard level. Level 2 can be assigned to BIM parts. If F ≦ 1-β, the usage frequency F is at a lower level, so the calculation unit 102j can assign level 1 to the BIM part. If 1 + α ≦ F <1 + β, since the usage frequency F is slightly higher than the standard level, the calculation unit 102j can assign level 4 to the BIM part. If 1 + β ≦ F, the usage frequency F is at a higher level, so the calculation unit 102j can assign level 5 to the BIM part.

  The calculation unit 102j associates the identification information (part identifier) of the BIM parts with the standard life years received from the terminal devices 400, 500, and 600 and the calculated usage frequency level, thereby managing the usage frequency level. Information 106h is created.

  For example, for the BIM part as shown in FIG. 4, the calculation unit 102j associates the identification information (part identifier) with the standard life years and the usage frequency level, and uses the usage frequency level as shown in FIG. Management information 106h is created. FIG. 4 is a diagram illustrating an example of a car model of an elevator. FIG. 5A shows the data structure of the usage frequency level management information 106h.

  For example, for the LED unit model 13 in the illuminating device model 12 of the car model 11 shown in FIG. 4, the calculation unit 102j obtains the usage frequency level as “5” and receives the standard life years “10”. As shown in (a), the identifier “ID1” of the LED unit model 13 is associated with the standard life years “10” and the usage frequency level “5” in the usage frequency level management information 106h.

  With respect to the interphone rechargeable battery model 14 shown in FIG. 4, the calculation unit 102j obtains the usage frequency level as “1”, and when the standard life years “3” is received, as shown in FIG. The identifier “ID2” of the model 14 is associated with the standard life years “3” and the usage frequency level “1” in the usage frequency level management information 106h.

  With respect to the landing switch model 15 shown in FIG. 4, the calculation unit 102j obtains a usage frequency level of “4”, and when receiving the standard life years “5”, as shown in FIG. The identifier “ID3” of the model 15 is associated with the standard life years “5” and the usage frequency level “4” in the usage frequency level management information 106h.

  With respect to the hold ashes model 16 shown in FIG. 4, the calculation unit 102j obtains a usage frequency level of “4” and receives the standard life years “5”, as shown in FIG. The identifier “ID4” is associated with the standard life years “5” and the usage frequency level “4” in the usage frequency level management information 106h.

  With respect to the governor rope model 17 shown in FIG. 4, the calculation unit 102j obtains a usage frequency level of “3” and receives the standard life years “11”, as shown in FIG. The identifier “ID5” is associated with the standard life years “11” and the usage frequency level “3” in the usage frequency level management information 106h.

  With respect to the main rope model 18 shown in FIG. 4, the calculation unit 102j obtains the level of use frequency as “3”, and when the standard life years “4” is received, as shown in FIG. The standard life years “4” and the usage frequency level “3” are associated with the identifier “ID6” and included in the usage frequency level management information 106h.

  The calculation unit 102j stores the created usage frequency level management information 106h in the storage unit 106.

  The predicting unit 102k predicts the life of the BIM parts based on the standard life years and the level of usage frequency. For example, the prediction unit 102k refers to the usage frequency level management information 106h stored in the storage unit 106, and acquires the standard life years and the usage frequency level of the BIM parts. The prediction unit 102k can correct the standard life years according to the level of use frequency, and obtain the corrected life years. When the usage frequency level is a standard level, the prediction unit 102k can set the standard life years as the life years as they are. When the level of use frequency is lower than the standard level, the prediction unit 102k can perform correction to reduce the standard life years to obtain the life years. When the level of use frequency is lower than the standard level, the prediction unit 102k can perform correction to increase the standard life years to obtain the life years.

  For example, as shown in FIG. 6, the correlation between the level of usage frequency and the ratio of the life years to the standard life years is experimentally acquired in advance and set in the prediction unit 102k. FIG. 6 is a diagram showing a life years prediction process, and shows a correlation used in the life years prediction process. In FIG. 6, when the usage frequency level is 3 (standard level), the standard life years should be used as they are, so the ratio of the life years to the standard life years is 100%. When the usage frequency level is 4 (slightly higher than the standard level), the standard life years should be slightly reduced to the life years, so the ratio of the life years to the standard life years is 80%. Yes. When the usage frequency level is 5 (a level higher than the standard level), the standard life years should be further reduced to the life years, so the ratio of the life years to the standard life years is set to 60%. Yes. When the usage frequency level is 2 (slightly lower than the standard level), the standard life years should be slightly increased to the life years, so the ratio of the life years to the standard life years is set to 120%. Yes. When the usage frequency level is 1 (a level lower than the standard level), the standard life years should be further increased to the life years, so the ratio of the life years to the standard life years is 140%. Yes.

  The prediction unit 102k supplies the determined life years to the maintenance plan table creation unit 102e. The maintenance plan table creation unit 102e creates a maintenance plan table by obtaining the replacement timing of parts based on the life predicted by the prediction unit 102k. The maintenance plan table shows when the life years have passed since the start of operation of the BIM parts as the replacement timing of BIM parts (maintenance work timing), and when the life years have passed since the replacement timing as the next replacement timing Show.

  For example, the maintenance plan table creation unit 102e creates a maintenance plan table as shown in FIG. 7A based on the life predicted by the prediction unit 102k. FIG. 7A shows the data structure of the maintenance plan table.

  Since the standard life years are “10” and the usage frequency level is “5” for the identifier “ID1” of the LED unit model 13 (see FIG. 5A), the ratio of the life years to the standard life years is set to 60. % Is specified (see FIG. 6), and the predicting unit 102k predicts the life span as 10 × 60/100 = 6 [years]. In response to this, the maintenance plan table creating unit 102e includes “life years” corresponding to the maintenance content “LED replacement” as 6 [years] in the maintenance plan table (see FIG. 7A).

  Since the standard life years is “3” and the usage frequency level is “1” with respect to the identifier “ID2” of the interphone rechargeable battery model 14 (see FIG. 5A), the ratio of the life years to the standard life years is expressed as follows. It is specified that it should be 140% (see FIG. 6), and the predicting unit 102k predicts the life years as 3 × 140 / 100≈4 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “interphone rechargeable battery replacement” as 4 [years] in the maintenance plan table (see FIG. 7A).

  Since the standard life years is “5” and the usage frequency level is “4” with respect to the identifier “ID3” of the landing switch model 15 (see FIG. 5A), the ratio of the life years to the standard life years is expressed as follows. It is specified that it should be 80% (see FIG. 6), and the predicting unit 102k predicts the life years as 5 × 80 / 100≈4 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “replacement of landing switches” as 4 [years] in the maintenance plan table (see FIG. 7A).

  Since the standard life years is “5” and the usage frequency level is “4” with respect to the identifier “ID4” of the hold ass model 16 (see FIG. 5A), the ratio of the life years to the standard life years is 80. % Is specified (see FIG. 6), and the prediction unit 102k predicts the life years as 5 × 80 / 100≈4 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “replace hold ass” as 4 [years] in the maintenance plan table (see FIG. 7A).

  Since the standard life years is “11” and the usage frequency level is “3” with respect to the identifier “ID5” of the governor rope model 17 (see FIG. 5A), the ratio of the life years to the standard life years is set to 100. % Is specified (see FIG. 6), and the prediction unit 102k predicts the life years as 11 × 100/100 = 11 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “replacement of governor rope” as 11 [years] in the maintenance plan table (see FIG. 7A).

  Since the standard life years is “4” and the usage frequency level is “3” for the identifier “ID6” of the main rope model 18 (see FIG. 5A), the ratio of the life years to the standard life years is set to 100. % Is specified (see FIG. 6), and the prediction unit 102k predicts the life years as 4 × 100/100 = 4 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “main rope replacement” as 4 [years] in the maintenance plan table (see FIG. 7A).

  In the example of FIG. 7A, when the maintenance content is “LED replacement”, since the life span is 6 years, the maintenance plan table creation unit 102e sets the operation start timing to October 2016 and every 6 years thereafter. Are marked in the maintenance schedule column with October 2022, October 2028, October 2034, and October 2040 as maintenance work timings.

  When the maintenance content is “interphone rechargeable battery replacement”, the service life is 4 years. Therefore, the maintenance plan table creation unit 102e uses December 2016 as the operation start timing, and then every four years in December 2020, 2024. The maintenance schedule column is marked with a circle with December, 2028, and December 2032 as the maintenance work timing.

  When the maintenance content is “replacement of landing switch”, the service life is 4 years. Therefore, the maintenance plan table creation unit 102e sets the operation start timing to March 2017, and thereafter, every two years, March 2021, 2025. In the maintenance schedule column, a circle mark is given as the maintenance work timing in March, 2028, and March 2032.

  When the maintenance content is “Hold Ashe Exchange”, the lifespan is 4 years, so the maintenance plan table creation unit 102e uses February 2017 as the operation start timing, and then every two years in February 2021, 2025 A circle is given in the maintenance schedule column with February, February 2028, and February 2032 as the maintenance work timing.

  When the maintenance content is “replace governor rope”, the service life is 11 years. Therefore, the maintenance plan table creation unit 102e uses October 2016 as the operation start timing, and then every 11 years from October 2027 to October 2038. With the month, October 2049 and October 2060 as the maintenance work timing, a circle is given in the maintenance schedule column.

  When the maintenance content is “main rope replacement”, since the lifespan is 4 years, the maintenance plan table creation unit 102e sets the operation start timing to October 2016, and then every four years in October 2020 and 2024. The maintenance schedule column is marked with a circle with October, October 2028, and October 2032 as the maintenance work timing.

  In addition, the maintenance plan table creation unit 102e re-creates the maintenance plan table at the timing at which the usage frequency level should be reviewed for the BIM parts included in the maintenance plan table (for example, at a periodic timing). Also good.

  For example, the calculation unit 102j recalculates the usage frequency level of the BIM parts when the control unit 102 determines that the usage frequency level should be reviewed (for example, periodic timing). Can do. The calculation unit 102j can assign any of the five levels as a level according to the recalculated value of the usage frequency F. The calculation unit 102j overwrites the usage frequency level management information 106h by associating the identification information (part identifier) of the BIM part with the standard life years received from the input unit 118 and the recalculated usage frequency level. Can be updated. For example, for the landing switch model 15 shown in FIG. 4, when the level of use frequency becomes “5” by recalculation, the calculation unit 102j uses the use frequency level management information 106h shown in FIG. Update as shown in (b). That is, the calculation unit 102j associates the identifier “ID3” of the landing switch model 15 with the standard life years “5” and the usage frequency level “5” and includes them in the usage frequency level management information 106h.

  The prediction unit 102k refers to the updated usage frequency level management information 106h and re-predicts the life years of the BIM parts. The maintenance plan table creation unit 102e recreates a maintenance plan table as shown in FIG. 7A based on the lifetime re-predicted by the prediction unit 102k as shown in FIG. 7B. For example, for the identifier “ID3” of the landing switch model 15, the standard life years is “5” and the usage frequency level is “5” (see FIG. 5B). It is specified that the ratio should be 60% (see FIG. 6), and the prediction unit 102k predicts the life years as 5 × 60 / 100≈3 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “replacement of landing switch” as 3 [years] in the maintenance plan table (see FIG. 7B). When the maintenance content is “replacement of the landing switch”, the lifespan is 3 years. Therefore, the maintenance plan table creation unit 102e sets the operation start timing to March 2017, and then every three years thereafter to March 2020. , March 2023, March 2026, and March 2029 are marked as maintenance work timings, with a circle in the maintenance schedule column.

  As shown in FIG. 7 (a) and FIG. 7 (b), the life plan is recalculated in accordance with the change in the frequency of use of the BIM parts and the maintenance plan table is recreated. The maintenance plan can be recreated to adapt to changes. For example, since the replacement timing of parts to be included in the maintenance plan table can be advanced in accordance with the increase in the frequency of use of the landing switch, it is possible to prevent the occurrence of problems due to the passage of the life of the parts. .

  Next, the operation of the BIM system 1 will be described with reference to FIG. FIG. 8 is a flowchart showing the operation of the BIM system 1.

  The shared server device 100 determines whether or not it is necessary to create or update the integrated BIM model (S1), and if it is not necessary to create the integrated BIM model (No in S1), the process proceeds to S8.

  When it is necessary to create an integrated BIM model (Yes in S1), the shared server device 100 transmits the creation conditions input by the user to the server device 200 (S2). The server device 200 receives the creation conditions (S3), creates the elevator BIM parts corresponding to the creation conditions using the part information stored in the parts information database 206a (S4), and creates the created BIM parts. It transmits to the shared server apparatus 100 (S5). The shared server device 100 receives the BIM parts (S6), and the elevator built-in building in a state in which the received BIM parts of one or more elevators are incorporated in the BIM model of the building stored in the BIM model database 106a. An integrated BIM model corresponding to the object is created (S7). The shared server device 100 transmits a registration request for the first information (for example, standard life years) to each terminal device 400, 500, 600 (S8). Upon receiving the first information registration request (S9), each terminal device 400, 500, 600 waits for input of the first information. When the first information is input from the user, each of the terminal devices 400, 500, and 600 transmits the first information to the shared server device 100 (S10). The shared server device 100 receives the first information and temporarily registers it in the storage unit 106 (S11).

  On the other hand, the shared server device 100 performs the simulation or the second information (for example, monitoring data, group management measurement data, periodic inspection data) transmitted (S12) from each terminal device 400, 500, 600. The second information is acquired by receiving (S13). Based on the second information, the level of use frequency of the BIM parts is calculated (S14).

  The shared server device 100 performs the processes of S1, S2, S6, S7, S8, and S11 and the processes of S13 and S14 in parallel with each other, and waits until both the completion of S11 and the completion of S14 are confirmed. When both the completion of S11 and the completion of S14 are confirmed, the shared server apparatus 100 obtains the identification information (part identifier) of the BIM parts of the standard life years received in S11 and the usage frequency calculated in S14. The usage frequency level management information 106h is created / updated in association with the level and stored in the storage unit 106 (S15). That is, the shared server device 100 registers the usage frequency level management information 106h corresponding to the first information received in S11 and the second information acquired (received) in S13 in the storage unit 106.

  The shared server apparatus 100 refers to the use frequency level management information 106h stored in the storage unit 106, corrects the standard life years according to the use frequency level, and predicts the life years of the BIM parts (S16). ). The shared server device 100 creates a maintenance plan table based on the life years predicted in S16 (S17), and transmits the created maintenance plan table to each terminal device 400, 500, 600 (S18).

  Each terminal device 400, 500, 600 receives the maintenance plan table (S19). The display control units 402d, 502d, and 602d of the terminal devices 400, 500, and 600 display the maintenance plan table on the display units 414, 514, and 614 (S20).

  As described above, in the embodiment, in the BIM system 1, the shared server device 100 calculates the usage frequency level of the BIM parts, and the actual lifetime years based on the BIM parts, the standard lifetime years, and the usage frequency levels. The maintenance plan table is prepared by determining the replacement timing of the BIM parts based on the predicted life years. The created maintenance plan table can be distributed from the shared server device 100 to each of the terminal devices 400, 500, 600 and displayed on the display units 414, 514, 614 thereof. As a result, the BIM system 1 can correct the standard life years and obtain the life years close to the actual value to create a maintenance plan table and distribute it to each terminal device, which is provided to owners, equipment companies, security companies, etc. It is possible to efficiently create the maintenance plan table to be improved and improve the accuracy of the replacement timing shown in the maintenance plan table.

  Therefore, for example, when the life of a part is shorter than the standard lifespan, it can be urged to replace the part with the shorter number of years. Safety can be improved. In addition, for example, when the life of a part is longer than the standard lifespan, it can be urged to replace the part with a longer number of years, so an increase in the running cost of the part can be avoided, and the part (BIM Parts) can be used effectively.

  In the embodiment, the case where the lifetime of the component is managed in units of years is illustrated, but the components may be managed in units of time other than years.

  In addition, when replacing parts due to deterioration over time, if the replacement part is discontinued, consider a replacement, but if the standard life of the replacement is different from the part before replacement, the maintenance plan will be reviewed. I need it. In other words, when replacing with a replacement product, it is necessary to review the plan each time in consideration of deterioration of parts over time, deterioration due to usage frequency, and the status of replacement products, and to distribute information to the relevant places. Therefore, when there is an input indicating that the BIM parts included in the maintenance plan table are to be replaced with other types of BIM parts having different standard lifespans, the maintenance plan table creation unit 102e receives the other types of BIM parts. Re-create the maintenance plan based on the standard life years of The re-created maintenance plan table is distributed from the shared server device 100 to each terminal device 400, 500, 600.

  Specifically, the calculation unit 102j has a standard lifetime year different from the standard lifetime years included in the usage frequency level management information 106h for each BIM part included in the maintenance plan table from each terminal device 400, 500, 600. In response to the reception by the shared server device 100, the usage frequency level of the BIM parts can be recalculated. The calculation unit 102j can assign any of the five levels as a level according to the recalculated value of the usage frequency F. The calculation unit 102j overwrites the usage frequency level management information 106h by associating the identification information (part identifier) of the BIM part with the standard life years received from the input unit 118 and the recalculated usage frequency level. Can be updated.

  For example, for the landing switch model 15 shown in FIG. 4, when the standard life time is changed from 5 [years] to 8 [years], the calculation unit 102j uses the usage frequency level management information 106h shown in FIG. Is updated as shown in FIG. FIG. 9A shows the data structure of the usage frequency level management information 106h before the update, and may be the same as FIG. 5B, for example. FIG. 9B shows the data structure of the updated usage frequency level management information 106h. That is, the calculation unit 102j associates the identifier “ID3” of the landing switch model 15 with the standard life years “8” and the usage frequency level “5” and includes them in the usage frequency level management information 106h.

  The prediction unit 102k refers to the updated usage frequency level management information 106h, and acquires the standard life years of the BIM parts and the usage frequency level. The prediction unit 102k corrects the standard life years according to the level of use frequency, and re-predicts the life years. The maintenance plan table creation unit 102e recreates a maintenance plan table as shown in FIG. 10A based on the life years re-predicted by the prediction unit 102k as shown in FIG. 10B. FIG. 10A is a diagram showing the data structure of the maintenance plan table before it is re-created, and may be the same as, for example, FIG. 7B. FIG. 10B is a diagram showing the data structure of the maintenance plan table after it has been recreated. For example, the standard life years is “8” and the usage frequency level is “5” for the identifier “ID3” of the landing switch model 15 (see FIG. 9B). It is specified that the ratio should be 60% (see FIG. 6), and the prediction unit 102k predicts the life years as 8 × 60 / 100≈5 [years]. In response to this, the maintenance plan table creation unit 102e includes “life years” corresponding to the maintenance content “replacement of landing switches” as 5 [years] in the maintenance plan table (see FIG. 10B). When the maintenance content is “replacement of the landing switch”, the service life is 5 years. Therefore, the maintenance plan table creation unit 102e sets the operation start timing to March 2020, and then every five years to March 2025 In the maintenance schedule column, ○ marks are given as the maintenance work timings, March 2030, March 2035, and March 2040.

  As shown in Fig. 10 (a) and Fig. 10 (b), the life plan is recalculated according to the change in the standard life of BIM parts and the maintenance plan table is recreated. The maintenance plan table can be recreated quickly in response to the change in the standard life span.

  Further, the BIM system 1 registers the deterioration image due to the aging of parts and the frequency of use in the shared server device 100, so that when the maintenance inspection date in the maintenance plan table is selected, the aging deterioration and use of the part at the time of the maintenance inspection date. You may come to be able to confirm the degradation image by frequency. Specifically, the BIM system 1 may perform the operation shown in FIG. FIG. 11 is a flowchart showing the operation of the BIM system 1.

For example, when the user (operator) selects the aging degradation image on the maintenance inspection date and browses the display units 414, 514, and 614, when viewing the part on the site, the part deteriorates over time. It can be judged more accurately whether or not. In addition, the display control units 402d, 502d, and 602d store the second information (for example, monitoring data, group management measurement data, and periodic inspection data) according to the aged deterioration images displayed on the display units 414, 514, and 614. A display for inquiring whether reacquisition is necessary is further displayed on the display units 414, 514, 614 (S26). When each terminal device 400, 500, 600 receives an input indicating that reacquisition is unnecessary from the user (worker) via the input units 418, 518, 618 (No in S26), the terminal device 400, 500, 600 ends the process. When each terminal device 400, 500, 600 receives an input indicating that reacquisition is necessary from the user (worker) via the input units 418, 518, 618 (No in S26), each terminal device 400, 500, 600 performs processing. The second information is acquired again (S27), and the process proceeds to S12. As a result, the use frequency level management information is updated (S13, S14, S15) triggered by re-acquisition / transmission of the second information according to the comparison between the aged deterioration image and the actual part image by the user (worker). ) Can be performed, the frequency of use frequency of the BIM parts can be appropriately reviewed, and the maintenance plan table can be appropriately recreated. That is, the maintenance plan table can be optimized (for example, optimized) in accordance with the level of use frequency.

  Further, the BIM system 1 may be configured to output an approximate cost when creating or reviewing a maintenance plan table when cost information of parts is input. Specifically, the BIM system 1 may perform the operation shown in FIG. FIG. 12 is a flowchart showing the operation of the BIM system 1.

  When each terminal device 400, 500, 600 receives an input from the user (worker) via the input units 418, 518, 618 that the second information need not be reacquired (No in S26), Wait for cost information to be entered. The cost information may include an amount required for one maintenance. When the cost information is input from the user, each terminal device 400, 500, 600 transmits the cost information to the shared server device 100 (S28).

  The shared server device 100 receives the cost information (S29), creates a maintenance cost table indicating a maintenance cost corresponding to the maintenance plan table using the maintenance plan table and the cost information (S30), and each terminal device. It is transmitted to 400, 500, 600 (S31).

  Each terminal device 400, 500, 600 receives the maintenance cost table (S32). The display control units 402d, 502d, and 602d of the terminal devices 400, 500, and 600 display the maintenance cost table on the display units 414, 514, and 614 (S33). For example, the display control units 402d, 502d, and 602d cause the display units 414, 514, and 614 to display a maintenance cost table as shown in FIG. FIG. 13 is a diagram illustrating a data structure of the maintenance cost table. In the maintenance cost table shown in FIG. 13, the cost (maintenance amount) is displayed in correspondence with the circled portion in the maintenance plan table of FIG. 7B, and the total amount for each month is displayed at the bottom line. ing.

  That is, since the maintenance cost table is created corresponding to the maintenance plan table that is optimized (for example, optimized) according to the usage frequency level, it is optimized (for example, optimized) according to the usage frequency level. The maintained maintenance cost table can be provided to the user (operator).

  Further, the BIM system 1 may be configured to automatically register standard life years and cost information by a dedicated reader (not shown). For example, the code analysis units 402h, 502h, and 602h of the terminal devices 400, 500, and 600 are pasted on the parts themselves and the storage containers corresponding to the parts that are alternative parts in S10 of FIGS. The code read by a dedicated reader (not shown) from the one-dimensional code or the two-dimensional code may be analyzed to obtain the identification information of the part and the standard life years. The code analysis units 402h, 502h, and 602h of the terminal devices 400, 500, and 600 correspond to the one-dimensional code or 2 attached to the part itself, the storage container, or the like corresponding to the part that is the substitute part in S28 of FIG. The code read by a dedicated reader (not shown) from the dimension code may be analyzed to obtain the identification information and cost information of the part. Alternatively, the code analysis units 402h, 502h, and 602h of the terminal devices 400, 500, and 600 are attached to the parts themselves or the storage containers corresponding to the parts that are alternative parts when the replacement parts are carried into the factory.
